Stops mid print?

HI having a problem where filament stops coming out about mid print. I check the temp when the filament stops coming out and it checks good. Checked all heater wires, ( I removed the old black heater wire connector in the past and replaced it with a good deans connector). and they all seem to be good. After filament stops I try to re run a load filament cycle and it works fine no clogs.  I am at a lose? I have a xyzpro chip resetter so I can try any temperature. I guess I will keep trying different temps.  any ideas?
